  abstract = {{A}im {T}he {I}ndo-{P}acific is the world's largest marine biogeographic region. {I}t is characterised by different degrees of connectivity among its subregions and harbours the majority of demosponge species currently known to science. {C}omparisons between regional sponge faunas have been undertaken in the past, mostly based on morphological species identification. {T}he {S}ponge {B}arcoding {P}roject, in tandem with regional {DNA} taxonomy campaigns, provides one of the largest {DNA}-based taxonomic data collections from sponges of the {I}ndo-{P}acific. {H}ere, we utilise the barcoding data in the most extensive molecular biodiversity study of sponges to date, which reveals patterns of shallow-water demosponge faunal connectivity, endemism and distribution in the {I}ndo-{P}acific with a level of resolution unavailable in prior morphology-based studies. {L}ocation {D}emosponge specimens in this study cover 13 marine provinces ({MP}s) of the {I}ndo-{P}acific. {M}ethods {W}e classified demosponge barcodes from 1910 sponge samples into 701 molecular operational taxonomic units ({MOTU}s) using 28{S} r{RNA}. {MOTU} composition of the {MP}s was compared based on {J}accard and {S} & oslash;renson dissimilarities and other biodiversity indices.{R}esults {O}ur data corroborated high endemism in {MP}s (up to 84.1% endemic {MOTU}s). {F}aunal overlaps are between the {R}ed {S}ea and the {G}ulf, which displayed small connectivity with other {MP}s in the {W}estern {I}ndian {O}cean. {T}he {W}estern {I}ndian {O}cean is a strong faunistic boundary to the {C}entral {I}ndo-{P}acific, to which the {P}olynesian sponge faunas were comparatively isolated as well. {M}ain {C}onclusions {O}ur data corroborate case studies on sponges that generally reject the presence of cosmopolitan or otherwise widespread sponge species, instead revealing high levels of regional endemism. {T}his is consistent with similar observations and hypotheses in other marine invertebrates, and highlights the need for close regional monitoring to identify biodiversity changes. {C}onnectivity among {I}ndo-{P}acific {MP}s differs for demosponges in many aspects from that of other marine taxa, hypothetically due to their shorter pelagic larval phase.},
